[Introduction]：E22-230T30D is a new generation of LoRa wireless module. It is a wireless serial port module (UART) based on SEMTECH's LoRa solution radio frequency chip. It has a variety of transmission methods and works in the (220.125~236.125MHz) frequency band (default 230.125MHz). LoRa spread spectrum technology, TTL level output, compatible with 3.3V and 5V IO port voltages.

|---|---|---|---|
| 1 | M0 | Input（weak pull-up） | Work with M1 to decide 4 working modes of module (not suspended, if not used, could be grounded). |
| 2 | M1 | Input（weak pull-up） | Work with M0 to decide 4 working modes of module (not suspended, if not used, could be grounded). |
| 3 | RXD | Input | TTL UART inputs, connects to external (MCU, PC) TXD output pin. Can be configured as open-drain or pull-up input. Ground |
| 4 | TXD | Output | TTL UART outputs, connects to external RXD (MCU, PC) input pin. Can be configured as open-drain or push-pull output |
| 5 | AUX | Output | To indicate module ’s working status & wakes up the external MCU. During the procedure of self-check initialization, the pin outputs low level. Can be configured as push-pull output (can be suspended). |
